Check valve with contoured body



FIG. 1 is a front elevational view of a check valve with contoured body, showing my new design;

FIG. 2 is a right side elevational view thereof, the left side elevational view being the same;

FIG. 3 is a bottom plan view thereof; and,

FIG. 4 is a top plan view thereof.

The broken line showing of unclaimed portions of the check valve with contoured body form no part of the claimed design. 

I claim the ornamental design for a check valve with contoured body, as shown and described.
